As short supply of raw cotton has raised raw material prices, in turn increasing the cost of production for cotton ginner, nearly 80 per cent of ginning units in Gujarat are shut since last month. The remaining are working part-time.

Thanks to lower arrival and raw high cotton prices, 700 to 800 units are not working now, say industry sources. Market estimates put the total number of ginning units in the state at around 1000. The units usually operate till April.
